Restlessness during sleep or waking up multiple times at night could be a sign of an underlying serious sleep disorder. If you find yourself tired even after a full night’s sleep or if your partner complains about your loud snoring while you are asleep, then this could be due to sleep apnea.

Sleep apnea is a potentially life-threatening health condition where a person suddenly stops breathing for a few seconds during sleep. It is important to have yourself evaluated by a sleep apnea specialist if you suffer such symptoms and this is more often noticed by your sleep partner.  Obstructive sleep apnea (OSA) increases the risk of high blood pressure while also putting you at risk of heart attacks, arrhythmias (irregular heartbeats), stroke and other cardiovascular diseases. 

What is sleep apnea?

Sleep apnea is a disorder caused by collapse or closure of your airway where breathing is repeatedly interrupted during sleep. This interruption can occur from anywhere between 5 to over 100 times in an hour! The pauses in breathing can last between 10 to 20 seconds, and sometimes as long as more than a minute. During sleep apnea, when you stop breathing, no oxygen enters the lungs, causing a drop in the level of oxygen in the blood. This leads to reduced blood oxygen supply to your brain, heart and other vital organs.

Sleep becomes disturbed in patients with sleep apnea which means that they do not get the deep restorative sleep which is needed for mental alertness and clear memory for a productive next day. Abnormal sleep patterns arise, consisting of frequent long pauses in breathing where the patient suddenly goes silent for a while, followed by a sudden loud gasping, choking or snorting episode when they start to breathe again. This becomes a vicious cycle night after night for prolonged periods, sometimes many years before the patient finally decides to seek medical help for his sleep problems. Sleep apnea needs medical intervention as it leads to many health problems and could even be fatal, leading to sudden death during one’s sleep. A person with the condition may not be aware, but anyone sleeping beside him or her can easily recognise the worrying symptoms of sleep apnea.  If your partner suspects you are a victim of sleep apnea, then you should consult an ENT specialist without delay.

What are the types of sleep apnea?

The most common is obstructive sleep apnea (OSA). During this condition, the inflow and outflow of air from the nose is blocked due to throat muscles relaxing and collapsing inwards while sleeping. This will result in loud snoring with recurrent pauses in breathing, night-time waking and gasping or snorting episodes. Another condition is central sleep apnea where the central nervous system is involved. In central sleep apnea, the brain temporarily stops signalling the muscles responsible for breathing to continue. Some patients may suffer from mixed sleep apnea which is a rare combination of both central and obstructive sleep apnea.

What are the causes of sleep apnea?

There could be many reasons for obstructive sleep apnea. Individuals who are overweight tend to have excess fatty tissue deposited just outside the throat. This causes the pressure on the inside of the throat to increase, especially when lying flat during sleep, causing the airway to collapse and close off. In addition, throat muscles can relax even further due to alcohol or medication use prior to sleep, worsening the airway obstruction. Presence of nasal obstruction from nasal allergies or deviated nasal septum, or enlarged tonsils or jaw deformities may also obstruct the airway. Asthma patients and smokers have a higher chance of sleep apnea. This condition is more common in males than women and it increases with age, although this condition may occur at any age.

What are the symptoms of obstructive sleep apnea?

The initial signs are complaints by your partner of loud snoring. Other signs to look out for include:

  • Headaches in the morning
  • Fatigue and tiredness throughout the day
  • Memory loss
  • Difficulty focusing or concentrating on the task at hand
  • Sore throat
  • Dry mouth
  • Mood and behavioural changes like irritability and bad temper

What are the health problems associated with obstructive sleep apnea?

In addition to impacting your quality of life, this condition can lead to the following health problems:

  • Hypertension (high blood pressure)
  • Heart attacks
  • Stroke
  • Depression
  • Dementia
  • Type II Diabetes
  • Irregular heartbeat (arrhythmias)

Early treatment can minimise the risk of developing heart attacks and strokes as complications of untreated sleep apnea.

How is obstructive sleep apnea diagnosed?

As there are many reasons why an individual might have sleep disturbances, it is not always easy for your family doctor to suspect that you have sleep apnea. A referral is usually made to an ENT doctor to examine the airway for signs of nose or throat narrowing. Taking your sleep partner along can be helpful as he or she will be able to give an insight on your breathing pattern while asleep and snoring episodes.

Your ENT sleep specialist will take a detailed medical history and perform a physical examination of your nose and throat. Your blood pressure and Body Mass Index (BMI) may also be checked. Additional tests like sleep studies may be needed to confirm the diagnosis.

Polysomnography is a sleep study where your heart, lung and brain activity patterns are measured and oxygen levels monitored while you sleep. Nowadays, most patients usually undergo a home sleep study with a portable device. This used to be done as a hospital-warded procedure where you might have to have yourself monitored all night but a home sleep study can now reliably provide enough good quality sleep data to accurately diagnose and detect sleep apnea.

What is the treatment for obstructive sleep apnea?

First and foremost, your ENT doctor will advise on lifestyle modifications. These include losing weight if you are obese, through a diet and regular exercise regimen. Avoiding alcohol and smoking especially prior to bedtime is strongly recommended. Nasal sprays and antihistamines may be prescribed if you have a blocked nose. If sleep apnea persists even after these measures, then personalised treatment measures will be considered to keep the airways open, with a thorough discussion about CPAP, surgery or a special mouthguard.

In CPAP or continuous positive airway pressure, a special machine delivers pressurised air through the nose and mouth via a fitted mask while the individual is sleeping. These devices help to keep the upper airway passages open while air is continuously pumped in. This prevents the symptoms of snoring and sleep apnea. This is the most widely used method to treat obstructive sleep apnea, but it may not suit everyone. Some people find it uncomfortable and may not attain the right fit. It is important to try different nasal  or face masks to find the right fit. Talk to your ENT doctor to check on what suits you the best.

Alternatives to CPAP machines are oral devices or mouthpieces which help to keep the throat open during mild to moderate conditions. Some devices hold the tongue in a different position. Nasal pillow masks are another option if you feel claustrophobic in masks that cover the entire face. Close follow-up helps to achieve successful treatment in patients with obstructive sleep apnea.

If none of these conservative methods work, then your sleep apnea specialist will suggest surgery where excess throat tissue will be removed in a procedure called Uvulopalatopharyngoplasty (UPPP). For very severe cases, upper airway stimulation is another method where an impulse generator detects breathing patterns and controls tongue movement but this is rarely used in clinical practice.

There are many treatment options for obstructive sleep apnea. What is important is to meet an experienced ENT physician without delay and discuss a treatment plan if you are diagnosed with sleep apnea. Dr. Annabelle Leong specialises in treating sleep apnea in Singapore and is a great ENT doctor to visit if you are suffering from sleep apnea.

Dr. Rajesh Bindal: Revolutionizing The Future Spinal Care

mm

Published

on

Spinal care is undergoing a period of change, driven by patient-centric demands, emerging technologies, and a more profound understanding of musculoskeletal health. Healthcare providers such as Dr. Rajesh Bindal are rethinking traditional surgical methods, focusing instead on minimally invasive techniques that prioritize faster recovery and lower complications. 

With tools like telemedicine and wearable tech, access to care is broadening, allowing for continuous monitoring and remote management of spine conditions. Simultaneously, data-driven diagnostics and AI are enhancing precision in treatment planning, while interdisciplinary collaboration ensures that care is comprehensive and personalized.

Minimally Invasive Techniques and Their Benefits

Minimally invasive spine procedures are becoming the preferred choice in modern care. Surgeons now rely on techniques that allow smaller incisions, leading to less tissue damage and quicker recovery times. Patients often return to daily routines faster compared to those who undergo traditional open surgeries, and the need for less general anesthesia further reduces associated risks.

Procedures such as endoscopic discectomy and laser-assisted spinal decompression are gaining traction in outpatient settings. These options carry fewer risks and often reduce the need for prolonged hospital stays. As a result, both patient satisfaction and clinical efficiency have improved immensely.

What once required long recovery periods is now being treated with same-day procedures. This shift is not only changing how surgeries are performed but also how treatments are integrated into overall patient wellness. The trend also reflects a broader shift toward value-based care models within the healthcare system.

Diagnostic Technology and Data-Driven Insights

High-resolution imaging tools like MRI and CT scans have become central to accurate spine assessments. These technologies provide detailed views of spinal structures, helping specialists detect abnormalities that might be missed through physical exams alone. In complex or chronic cases, such imaging helps trace the root of persistent symptoms more effectively.

Artificial intelligence is adding another layer of precision by analyzing patterns in imaging data and patient history. With AI-assisted tools, clinicians are developing more targeted treatment plans that account for individual anatomy and risk factors. Early intervention is now more achievable thanks to these innovations. When spine conditions are caught in earlier stages, patients often avoid surgery altogether or benefit from less invasive interventions.

Expanding Access Through Telemedicine and Remote Care

Virtual spine consultations are helping bridge the gap between patients and specialists, especially in rural or underserved regions. Video-based appointments allow for quicker evaluations, timely follow-ups, and better continuity of care without requiring travel. These innovations have proven especially useful during times when in-person visits are limited, such as public health emergencies.

Wearable devices that track posture, movement, and pain levels are now contributing to real-time monitoring. These tools give providers valuable data that can influence treatment decisions, especially when in-person visits are limited or unnecessary. Remote apps also help patients stay consistent with prescribed rehabilitation exercises.

Despite these advancements, some cases still demand hands-on assessment or surgical intervention. The key lies in blending digital convenience with careful clinical judgment to ensure patients receive the most appropriate care. Providers must be trained to know when to escalate care to in-person settings, ensuring patient safety is never compromised.

Putting Patients at the Center of Spinal Care

Modern care is moving away from one-size-fits-all approaches. More providers are focusing on understanding a patient’s lifestyle, goals, and emotional well-being as part of the treatment strategy. Addressing the mental and physical aspects of chronic spine pain leads to more sustainable outcomes. This approach empowers patients to become active participants in their recovery.

Integrated care teams that include physical therapists, pain management specialists, and behavioral health professionals are becoming more common. This collaboration helps patients stay engaged in their recovery and builds a stronger therapeutic alliance between providers and individuals. Response to treatment tends to improve when patients feel heard and supported throughout the process.

Training, Innovation, and Future Directions

Medical training is evolving alongside advancements in spine care. Surgeons and clinicians are learning to work with robotics, navigation systems, and biologics that weren’t part of traditional education just a decade ago. Simulation-based learning and virtual reality platforms are also being used to enhance skills.

As new therapies emerge—from regenerative injections to AI-assisted surgical robotics—ongoing education is crucial. Providers must not only master new tools but also develop communication skills that allow them to explain complex options in relatable terms. This new wave of technology demands both technical proficiency and empathetic patient interaction.

Looking ahead, policy reforms may further shape access and innovation in spine treatment. These changes could influence everything from insurance coverage to how new procedures are adopted in mainstream care. Continuous collaboration between clinicians, tech developers, and policymakers will be essential to ensure the best outcomes for patients.
